Hisense A6N vs Samsung OLED S95H (S99H) (QD-OLED)

Unfortunately, the HDR effect quality on A6N is not impressive. A peak brightness of 250 nits doesn’t allow for spectacular highlights, and HDR looks rather muted, more like ordinary SDR. This will not satisfy more demanding users who want to enjoy high-quality movie content. Additionally, the color gamut coverage is not very impressive either: DCI-P3 at 82% is an average result that doesn’t let you fully enjoy vivid colors in HDR material.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in movie scenes can exceed 2800 nits! Regardless of the scene, you can count on powerful HDR effects that practically blind you, and that's exactly what we expect from a top-tier screen. It's inherent to OLED panels that in very bright, full-screen shots they won't sustain as high a brightness as they do with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H was able to maintain higher brightness than most Mini LED screens on the market. In terms of brightness, the S99H is currently the best OLED TV we've tested.

Color gamut coverage

The S99H also handles color exceptionally well, which is a direct result of the QD-OLED panel used here. Regardless of the test scenario, whether synthetic test patterns or measurements with film material in the background, the results stayed at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the most demanding color space it reaches nearly 90% of BT.2020. That's top-tier performance on the market. These results match what we saw in the new SQD-Mini-LED screens, and in real movie scenes they even outperform RGB Mini LED displays.

In the color reproduction category, the Hisense A6N in Filmmaker Mode leaves much to be desired. Although the mode's name suggests we should expect faithful movie color reproduction, the reality is different. The TV has significant picture quality problems. The white balance issue is particularly noticeable for both HD and 4K material, as it is heavily skewed by a dominance of blue. This results in artificial, cool tones, clearly visible in the comparison photo below. The ColorChecker test further confirms these errors, which are compounded by low color gamut coverage.

The gamma luminance curve shows a serious problem maintaining the 2.4 level, with the plot well below the reference value. That leads to excessive image brightening and washed-out blacks. The EOTF curve for 4K material also indicates brightness problems. At the low end there is a pronounced bump caused by the TV's excessive brightening, which negatively affects picture quality. This image behavior prevents fully enjoying movies and requires manual correction.

Samsung offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor shortcomings. This mainly concerns a slight drift in white balance in SDR content and a slightly low gamma. As a result, in a darker room the image can be a bit too bright relative to the reference gamma of 2.4, which is the standard for watching films with the lights off. These are of course small issues, since overall color reproduction remains very good and the errors in ColorChecker measurements are small. However, we know that from a screen of the S99H's class you can and should expect even more, so we had it professionally calibrated.

Hisense A6N offers in its settings options and tools to adjust many picture parameters, which we used. As for the white balance, we managed to remove the excess blue; this is clearly visible in the comparison photo below, where the boy in the image practically "comes to life". A large improvement can also be seen in the gamma brightness response, as the TV no longer has serious issues with overbrightening the entire picture. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to this model's exceptionally low brightness. For HDR content we use dynamic tone mapping, which allows recovery of many details despite lifting the midtones. For this TV that brings more benefits than drawbacks. The errors that remain visible in the color gamut test and the ColorChecker for 4K content stem from the low color gamut coverage and are difficult to eliminate because of the TV's characteristics. Even so, the image tonality is much better, so we recommend calibrating the factory settings, which are far from ideal.

After professional calibration, FILMMAKER mode looks virtually perfect. Because Samsung offers a rich set of advanced calibration features, we were able to tune the colors to an almost perfect level. Most importantly, we were able to even out the white balance and the gamma curve, which resulted in noticeably better contrast and a more natural image dimensionality. With a profile prepared like this, there's really nothing to nitpick or call a flaw. After calibration, the S99H is capable of delivering an essentially reference-quality image.

Let's see how A6N handles low-quality material. When it comes to smoothing tonal transitions, the lack of a function to reduce posterization or smooth tonal transitions in low-quality sources, such as broadcast TV or DVD, may be noticeable to more demanding viewers. As for digital processing, the model was rendered correctly and the branches were free of the typical jagged edges. The image has a pronounced sense of plasticity and is soft, which may appeal to those who prefer that kind of picture style.

The proprietary Samsung NQ4 Gen3 processor handles upscaling and digital image processing. It does a very good job scaling lower-resolution material to 4K. The picture is sharp but doesn't look artificial or overly sharpened. The only fairly specific drawback appears with very old footage shot at 480p or lower. In those cases the TV can slightly crop the edges of the image.

The processor also copes quite well with artifacts visible in low-bitrate material, for example heavily compressed YouTube videos. The noise reduction feature effectively smooths the image and reduces posterization, but it works rather aggressively. It can remove not only unwanted artifacts but also some fine details and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image over keeping every detail, it can be useful.

The 60 Hz panel in Hisense A6N will likely please people who enjoy watching movies, because the TV offers an "ultra motion smoothing" feature that lets you adjust the image's motion, making it choppier or smoother and more cinematic. As for motion blur, it is rather average. You can see quite noticeable blur, especially on dark backgrounds, which is a common trait in this class of TVs.

Another major advantage of OLED panels is excellent motion reproduction. Thanks to the pixels' near instant response time, the Samsung S99H practically produces no smearing. Fast-moving objects don't show noticeable halos or trailing artifacts, so the TV performs very well for both watching sports and gaming. One quirk of OLED screens compared with LCDs is how they render low frame rate material. With very slow camera movement the image can appear noticeably more stuttery. This can be quite effectively mitigated using a frame interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, making it easy to find a compromise between smoother motion and preserving the cinematic character of the content.

Hisense A6N is a TV that will likely appeal to casual gamers, mainly because of its 60 Hz panel, which may not satisfy more demanding players. Still, it offers several features that can make gaming more enjoyable. The TV supports functions such as ALLM (automatic low-latency mode), VRR (variable refresh rate) and Dolby Vision, which let you enjoy better picture quality and smoother motion in games that support those technologies. Moreover, the low input lag means in-game reactions are fast, which is crucial, especially in fast-paced titles. Thanks to these features, although the TV isn’t the ideal choice for demanding gamers, it provides solid support for those who value comfortable gaming without complicated settings. It’s an ideal solution for people who want to enjoy gaming without high hardware demands while still having access to modern technologies that enhance gameplay quality.

Samsung S99H is also an excellent TV for gamers. It offers almost every useful feature... well, maybe except the obvious lack of Dolby Vision for Xbox consoles. It's equipped with four fully functional HDMI 2.1 ports with the full 48 Gbps bandwidth. Thanks to that we can easily use frame-rate synchronization VRR and automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and without unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the mini-map, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung's feature: Game Motion Plus. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared to the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g., GTA 6 😉) that runs at only 30 frames per second on console, the S99H can display it much more smoothly than competing models.
